Hi Eagle,
Please considered getting a DRV8860EVM to compare the transactions against yours.
Also, please disconnect the loads if possible.
Then perform a data register write and data register read using Figures 12 and 25 of the datasheet. Is this…
Hi Stephen,
The source code can be found in the DRV8860EVM_MSP430_FIRMWARE.zip file in the Hardware files of the DRV8860EVM.
The direct link is: http: //www.ti.com/lit/zip/slvc596
You can look further into it to determine if it meets your functional…
Other Parts Discussed in Thread: DRV8860 , DRV8860EVM Hi,
I am using DRV8860 in my design to drive 8 valves. These valves consume a current of 500mA during pick up and during hold, I can maintain them at 40% (200mA). One strange observation I made about…
Hi Kathie,
It is recommended to place one bulk 10uf and one 0.1uf cap around each DRV8860.
I have to get back to you on the maximum number of chips in series? Do you have an estimate on how many you would like to use in series?
If you have not done…
Hi Tony
TLC5940 is more like a dedicate LED driver which has less capability to driver a stepper motor. Both the output current and the capacity of internal free wheel diodes are reaching or beyond the limit in motor application.
The unipolar stepper…
